** HMS Calorimeter efficiency study. attachment:Vijay_May11_2023.pdf

** It looks like the efficiency is less from the production data (Q2 = 0.38 GeV2, High e).
103
** I'll take a look at the heep coin data in this run period of the experiment and get the efficiency. 
104 547 Ali Usman
** Hopefully that's number, the efficiency from heep coin data, will be reliable to correct the inefficiency of the detector and correct the data run by run.

** Carlos has been working on the rate dependence issue for the luminosity scans that Casey and I have been seeing. He came to a similar conclusion as me that there will need to be a correction factor that we all agree on that will need to be applied. We are meeting on Monday to discuss things further. "See his slides on the docDB":https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1206
215 509 Nathan Heinrich
** I think I have tracked down the odd issues with right setting that I have been seeing for most energies. I am not sure why, but it seems that something is going wrong with the replays. I tried rerunning them, but the issue has persisted. My initial guess is that it may be an issue with the TDC cuts, since the coin time distributions were looking off previously.

** SIMC code was updated to match what is in hcana, using hcana and parts of Carlos' code as a template. Things do not look right though. 
362
** We are a month behind at this point and Bill has finally responded to my questions so I am going to fully concentrate on getting cross sections before the Hall C collaboration meeting in January so that Nathan can present them. I am setting a soft deadline of January 6th to get him early results but will continue to push for cross sections by the talk.

** Fits for lumi scans look great for HMS across the board. SHMS no track also look pretty good but tracking still needs work. Ali has adjusted the tracking parameters in the replay which should help things. Signs of boiling are also now evident in HMS for some runs.
406
** Odd issue with the yields going on that I need to discuss with Bill. It seems to be a cut discrepancy that is eliminating events, I may be missing a cut that he has hidden somewhere. Besides this, the cross-section code is being edited for HeeP so we can get some cross-section plots on this soon.

** Heep Coin Offset study using Peter Bosted's correction factor for HMS central momenta. The results from 8.2 and 10.6 GeV improved after applying the offset whereas 6.2 over corrects the distributions as they are already looking good with no offset. Data and SIMC comparison look very good for W distribution but doesn't perfectly match for missing variables.

** Regarding Ali's work on the Pc offsets at high momentum, I referenced the delta corrections I made early last year. In EPICS, the NMR did not appear to be locked and in the middle of the scan, the NMR was changed. Slide 15 has the offsets to the central momentum, Pc.

** I have debugged all of the issues I was having with Bill's code. I am now in the process of merging the two frameworks which is mainly just making names, conventions, etc. consistent.

** Fixed some issues with the luminosity scripts with updated replay and analysis script. The biggest issue was the really low beam on times which came from BCM4a being called by accident in some cases instead of BCM1.
486
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
487
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.

** Lumi SHMS tracking is still showing the trend from 9/8. It was found that the lumi replay script is not updated with many of Ali and Richard's most recent changes. These changes are being applied and a set of new replays will be done.
506
** Bill's cross-section code is broken into two major parts. The root analysis part, which takes all the yields, uncertainties, etc., is nearly complete with the connecting ltsep framework script finishing up. The second part, where many of the final plots and cross-sections are done, is a hard-coded mess. Richard is in the process of making this more dynamic. This aspect will take more time but the root analysis part is the bulk of the analysis anyways.

** Heep Coin analysis for high Q2 KaonLT data (6.2, 8.2, 10.6 GeV beam energy) has now all the efficiencies/live times applied. The results for all 3 beam energies are looking very good. Data/SIMC ratios are agreeing very well (< 3%) and the shapes are matching up nicely. Next step is to finalize offsets for both low and high Q2 KaonLT data. Also proton absorption correction and target boiling needs to be applied.

852
** The explicit calculation of the prescale has hit a snag because of the differences between 6 GeV and 12 GeV. I contacted Mark Jones, who explained there are significant differences in the ADC gate between the two eras (which my own findings confirmed). I have contacted Brad for further input.

** PID efficiency script is coming together
1080
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1081
*** Hcal cut should be changed to cut around the mean normalized value instead of cutting above or below it only. This will assure electrons aren't lost.

** The calibrations are nearing completion with only the HG Cherenkov and SHMS calorimeter yet to be finished. There are also smaller issues with some DC and HMS calorimeter runs.
1138
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1139
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1140
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1141
** We can begin looking forward towards efficiencies. 
1142
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.

1200
** The time window is easier to set now.
1201
** DC has been fine (since it uses TDC)
1202
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")

1207 1 Richard Trotta
** Two major issues...
1208 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1209 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1210 67 Richard Trotta
## Timing offset between EL-REAL and 3/4 is 130 ns which causes junk tracks at high SHMS rates (~6% of the time)
1211
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1212
** Richard has been checking for bugs in the code. 
1213
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

1217 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values

* Richard
1355
** Discussed with Mark Jones and is cross checking his January luminosity scan analysis against Mark's. Realized that BCM calibrations (gains, offsets etc) are different - currently working on fixing that, presents current results - low curent point is ~10% below unity, discussion that this seems to indicate that BCM offsets are the issue as low current points would be most sensitive, is planning to also double-check the BCM calibration procedure - had discussion with Dave Mack at JLab
1356
** Presents a script developed for luminosity scans that determines yields for a run number input on command line. Discussion this could be good to adapt for kaon counting during experiment.

* Luminosity scans (Richard, Ryan)
1371 35 Stephen Kay
** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies
1372
** Carbon scans from January (low rates) have large deviations from unity, in particular behavior at higher currents (>40uA), e.g. cpu dead time, that is not yet understood
1373 1 Richard Trotta
** discussion about pre-scale factors
1374 35 Stephen Kay
1375
* Discussion about Richard's script extracting and printing information from report files and trees including histograms
1376
** Add option for looking at yields with cuts on cointime, target window, and missing mass
1377 1 Richard Trotta

* H(e,e'p) kinematics investigation for fall run (Samip)
1380 1 Richard Trotta
** Optimal range is between electron angles of 17-20 degrees, time required ranges from ~1 hour at 17 degrees to ~3 hour at 20 degrees, other angles may be of interest for disentangling charge and current dependent effects

* Luminosity Scans January 2018 (Richard)
1396
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1397
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1398
** Efficiency calculation was investigated in detail and applied using scalers from trees
1399
** Results for carbon (normalized to 30uA) show large variation - need to understand
1400
** *Next steps:*
1401
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1402
*** Check stability of pre-scale (Ryan saw changes within runs)
1403
*** Check if detector calibrations for runs are implemented correctly
1404 1 Richard Trotta
*** Analyze with Ryan's cuts
1405 35 Stephen Kay
1406
* Luminosity Scans April 2018 (Ryan)
1407
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1408
** Tracking-based analysis for runs 2073-2095
1409
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1410
** Included most recent detector calibrations in replay of these runs
1411
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1412
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1413
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1414 5 Richard Trotta
** *Next steps:*
1415 35 Stephen Kay
*** Check tracking efficiency
1416
1417 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
1418 35 Stephen Kay
** April 2018 scans show hydrogen and deuterium target boiling on level of 3-4%, Carbon is consistent with no boiling, as expected - based on description, new targets are expected to have less boiling than those used previously, e.g. in FPI2. Double check this.
1419
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1420
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1421
** Uncertainties on current
1422 1 Richard Trotta
** Detector calibrations
1423 35 Stephen Kay
** HMS vs. SHMS
1424
1425
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1426
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1427
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1428
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1429
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1430 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1431 2 Richard Trotta
** *Next steps:*
1432 35 Stephen Kay
*** Look for a run with kaon momentum closer to 3 GeV/c (aerogel threshold is ~3 GeV/c for kaons for n=1.015)
1433
1434
* Yield normalized ratios from SIDIS (Hem)
1435
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1436 4 Richard Trotta
** *Next steps:*
1437
*** Check if efficiencies, currents, run time etc. are taken into account correctly

1445
* Discussion luminosity scan analysis (earlier scan) - Richard
1446
** Shown is a scaler-based analysis using scalers from report file and from ROOT tree - the values are different, why that is has to be checked
1447
** Notes on efficiencies in report file:
1448
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1449
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1450
*** Tracking efficiency needs to be checked
1451
*** 3/4 trigger efficiency seems ok
1452
* Discussion luminosity scan analysis (later scan) - Ryan
1453
** Fewer carbon runs than earlier scan
1454 111 Richard Trotta
** Shown is a tracking-based analysis using data from the ROOT trees
1455 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1456
* SIDIS analysis - Hem
1457
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1458
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1459
* Analysis of exclusive events in SIDIS - Samip
1460
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1461
** Ongoing work on implementing coincidence time into tree
1462
* Discussion of run plan, and in particular possible low Q2/low energy
1463
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1464
** For pion form factor and LT, have two possible settings that can use the prescribed beam energies: Q2=1.45 and 0.35 GeV2 - prioritize towards the higher Q2 as not as sensitive to offsets
1465
** Garth will put this together in a draft email

1483 35 Stephen Kay
1484
*  Discussion of Andres' slides on elastic W calculation in hcana - initial issue with negative W values seems to be due to outdated information in standard.kinematics file. Additional investigation ongoing.
1485
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1486
* Discussion of Richard's slides on run plan kinematics and preparations -
1487
** everyone agrees that in general want to have as many L/T cross section separations as possible in a robust run plan balancing statistics vs. systematics
1488
** before actual run may want to do a 3D optimization in all kinematic variables to get the best possible delta(epsilon) for the L/T separations
1489
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1490
** kinematics plots W-Q2 show that still need to do some optimization
1491
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
